How to Disable Gatekeeper from Command Line in Mac OS X

Though most Mac users will want to keep Gatekeeper enabled for security purposes, some advanced users find that Gatekeeper is overly zealous in preventing third party apps from being used in Mac OS X.

While it’s easy to turn off Gatekeeper through the System Preferences on a Mac, another option is to disable Gatekeeper by using the command line in Mac OS X. This can be helpful for scripting purposes, configuration, remote management, and just for those who prefer to use the Terminal.

Disable Gatekeeper from the Command Line in Mac OS X

Launch Terminal if you haven’t done so yet (/Applications/Utilities/) and issue the following command to turn off Gatekeeper:

sudo spctl --master-disable

Hit return and enter the admin password as usually required by sudo, and Gatekeeper will instantly be disabled. If you feel like confirming this, you can do so with the –status flag and the same command, like so:

spctl --status

This will report back ‘assessments disabled’ to indicate that Gatekeeper has been turned off. You will also find that the Gatekeeper Security preference panel will be set to ‘Everywhere’.

How to Enable Gatekeeper from the Command Line of Mac OS X

Of course, you can also turn on Gatekeeper from the command line of Mac OS X too by using the following command string:

sudo spctl --master-enable

Hit return and you can confirm the status again with –status:

$ spctl --status
assessments enabled

Gatekeeper will be enabled again at it’s strictest setting. As disabling, the setting will carry through the GUI as well.

Again, most users should leave Gatekeeper turned on, and if need be, they can bypass it through the System Preference panel on a per-app basis, or by using the right-click “Open” trick.

So after I type in “sudo spctl —master-disable” w/o the quotes, I hit enter and when it says password I type in my password I get a message saying “command not found”. Now what do I do??? Please help thx

If I type “jarvis” into the command line it also says command not found, because it’s not a correct command. So I’d start by using the proper command for spctl. But if you can’t use the command line correctly than I would say this is too advanced for your technical skill level, that’s no big deal just accept and move on. I don’t go messing around with my cars engine for example, I take it to an expert. Computers are similar. Gatekeeper is there for a reason, if you can’t type syntax correctly you definitely don’t want the end result.

I inserted the recommended command in terminal and I checked that Gatekeper is disabled but Sierra still can not open unsigned apps.When I click or right and open simply do nothing. What I have done wrong?

No not really, it just means you turned it off at some point, probably to get rid of the warning when opening apps from the web and third parties. Fine for advanced users, average users best to keep Gatekeeper on.
